Abstract: The blocking transducer has a transformer (TRA) with at least one primary winding and at least one secondary winding (WSE), whereby the primary winding is connected in series with a controlled switch to an input d.c. voltage and a rectifier (GLR) and charging capacitor (LAC) are connected after the secondary winding. A switch drive circuit, which receives a control signal derived from the flux change in the demagnetization phase, opens the switch at the end of the magnetization phase and closes it after demagnetization of the core. The transformer has first and second primary windings (WP1,WP2), each connected via one of two switches (CS1,CS2) controlled by one of two drive circuits (AS1,AS2) to one of two input d.c. voltages (UE1,UE2).

Title: Sound-absorbing structure
IPC: E01F8/00
Filed: 1982-02-04
Granted: 1988-02-10
Abstract: The invention relates to a sound-absorbing structure with a supporting construction and with a sound-permeable, dimensionally stable outer skin in the form of a grating or netting, which is of a compliant form and contains a filling of refuse compost, which allows planting or cultivation of greenery on the sound-absorbing structure, the apparent density of the refuse compost preferably being 600 to 900 g/l. Such a structure is intended to have high intrinsic stability along with optimum sound absorption, so that a weight-saving supporting construction can be used. This is achieved by the supporting construction being arranged entirely inside the outer skin 6 and having at least one substantially perpendicular upright 1, which can be anchored in the ground and has in its upper region a cross-strut 2 and in its lower region a cross-arm 3, which is mounted pivotably about a substantially horizontal axis 4 and can be fixed in two or more positions, and by the outer skin 6 being fastened on the one hand to the cross-strut 2 and on the other hand to the cross-arm 3, in particular to the outer free ends of the same. <IMAGE>

Abstract: Inside a flexible shell (10), a deformable pocket (20) is connected to blood circulation via an inlet valve (30) and an outlet valve (40). The pocket is compressed by a floating assembly comprising a drum (50), and a bracket (60) rotatable about the axis thereof. One of the edges (21) of the pocket (20) is fixed to the drum (50); the opposite edge (22) is connected to the bracket (60) by a traction link (70), for example an inextensible sheet. Relative rotation between the drum and the bracket over a fraction of a turn enables the pocket (20) to be wrapped around the drum (50) and the assembly returns to its starting position under the effect of venous pressure. The disposition of the various components provides a self-adapting lever which limits mechanical losses to rolling friction between the drum and the pocket.
